Next time on Zestology:

I speak to celebrated NYT bestselling author Gretchen Rubin on upgrading some of our habits. Like:

• How to read more
• How to get over decision fatigue
• And how to pass the toothpaste test (we basically invented this during the podcast. I think it could catch on.)

It's an illuminating interview, and I REALLY learnt a lot. Thanks Gretchen - and see you at the weekend for the full interview.
